CARDlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 323,021, dated July 28,1865.

Application filed September 1, 1884. (No model.)

To all whom it may concern.-

Be it known that I, PHILIP T. BEGLEY, of Newton Upper Falls, in thecounty of Middlesex and State of Massachusetts, have invented anImprovement in Oarding-Machines, of which the following description, inconnection with the accompanying drawings, is a specification, likeletters on the drawings representing like parts.

In carding-machines for carding cotton the main cylinder is driven fromone source, and is usually kept in constant rotation; but the doffer,feed-rolls, and railway-head are driven from anothersource andstartandstop together. When,forany cause/therailway-head is stopped the dofferand feed-rolls are also stopped, but the main cylinder continues tomove, and in its rotation acts to strip the cotton from the teeth ofthat part of the then stationary doffer opposite or in contact with theteeth of the main cylinder, and at the same time the cotton so detachedfrom one part of the doffer is accumulated thereon immediately belowthat part of the doffer next the card, and thus the doffer haslongitudinally upon it a sort of lump or roll of cotton. In thiscondition,when the railway-head, doft'er, and feed-rolls are againstarted, and especially if the doffer had been stopped for a fewmoments, the sliver, being removed from the rotating doft'er My thecomb, is parted at or near that part of the doffer which, when thelatter was stationary, was in contact, as stated,with the teeth of themain cylinder. 1

The chief object of my invention is to enabl the doffer and railway-headto be stopped and started at will without interfering with thecontinuity of the sliver to be thereafter removed from the doffer by thecomb. To do this Ihave provided means whereby the (letter, when it is tobe started,is automatically turned or rotated backward foraportion of arotation sufficient to carry the teeth which were stripped, as stated,and the accumulated bunch of sliver past the point of contact betweenthe doffer and main cylinder, and'thereafter the doffer commences toturn in its proper working direction. The reversal of the direction ofrotation of the doffer just before commencing 50 to operate regularlyenables the stripped part thereof and the part on which there is toomuch cotton to be again brought into regular contact with the maincylinder, so that the stripped part of the (letter receives cotton fromthe main cylinder, and the accumulated fiber on the doffcr is in ameasure broken up or spread, whereby the film of cotton on the doffer isleft in such condition as to enable acoutinuous sliver to be taken fromit by the usual comb.

My invention consists, essentially, in the combination, with the maincylinder and doffer, of mechanism to automatically reverse the movementof the doffer for a short distance prior to starting to turn the same inits regular forward direction, whereby the entire toothed surface of thedotfer is provided with cotton, thus avoiding the parting of the sliveras it is removed from the doffer.

Other features of theiiwention i "it. here- 70. inafter specificallypointed out in the claimsat the end of this specification.

Figure l is an elevation of a suflicient portion of one side of arailway-head and the delivery end of a carding-machine to enable my 7 5invention to be understood, the box and belts for carrying the sliverfrom the carding-machine to the railway-head being omitted, as they areplainly shown in other figures, a por tion of the doffer casing or coverbeing broken 8o away. Fig. 2 is a partial top or plan view of Fig. 1,the railway-headabove the line :vwbeing removed, a portion of the casingor cover being broken away. Fig. 3 is a section in the line or m, Fig.1, looking toward the left, and Fig. 4 is an enlarged detail of a formof clutch or reversing mechanism which I have selected for use. I

The main cylinder A, top flats, A, framework A, doffer B, trumpet B,rolls B, sheave B, adjustable guide B, box 0, condensing-roll C, belt 0shaft D, pulley D, belt D pulley D pinion D, gear D 'on the shaft of thedef fer, bevel-gear E, bevel-pinion E, sprocket- I wheel 2, chain E,sprocket-wheel 3, the toothed 9 5 gear 4, to which it is secured, thestand 5, roller-stands G and rolls G of the railwayhead, (the lower onesonly being shown,) the gear G, shafts G and H, and the gears 6 7 8 areall substantially as now commonly in use, I00

so need not be herein particularly described. The shaft H is providedwith two pulleys, j" and Z, the pulleyl being loose and placed next theframe 1-11 of the railway-head. The shaft H has fast upon it the clutchpart (1 and the collar 7), and between them the said shaft is providedwith a loose quill, hub-shaped, to constitute a gear, 14, with clutchparts a. a." at each end, the quill havingan annular groove, 10, toreceive a forked arm, 12, fastened to the clutch-shifting slide-rod 13,having suitable hearings on the frame of the railway-head. Between thecollar I), referred to, and the quill I have placed on the said shaltloosely a toothed U gear, 0, having attached to it at one side a clutchpart, a. The quill. with clutch-teeth at each end, may be movedlongitudinally on the shalt H between the clutch parts (1V and a to thuscause one or the other of the ends of the quill to be engaged by one orthe other of the clutch parts (I. or u", and be rotated in one or theother direction, as will be described. The loose pulley I, about whichthe drivingbelt for the railwayliead and dofl'er extends, while the headand doli'er are stopped, and which pulley is thus at such time keptruuhing, has a sleeve provided with a pinion, Z, which, through anintermediate, Z", engages a pinion, (1,011 and rotates the shalt 1/,provided with a toothed wheel, (1", which, by its engagement with,rotates the toothed gear a, referred to.

The clutch-shifting slide-bar 1.; is provided with. a collar, 18, andbetween the latter and the side frame of the railway-head the said baris surrounded by a spiral spring, ll), which normally acts to keep thesaid bar pressed toward the right, as in Figs. 2 and 4, thus, throughthe linger l2, keeping the right-hand end of the quill, as in saidligures, in operative engagement with the clutch part a, fast on theshaft H, and at such time, if the shaft is rotated by the belt on thefast-pulleyf, the quill will be driven by the clutch part a in thedirection to effect the regular forward rotation of the dofier, thetoothed hub 14 at such time turning the gear 4 to drive the chain E andshaft D, and at the sametime, by reason of the bevelgear 8 on the shaltll, the rollers of the railway-head are driven in the proper andcustomary direction for regular work. The slideaar 13, at its outer ond, has joined to it a hand- .ever, 6, pivoted at c.

Therailway-head will be provided with the usual beltshifting mechanism,(not shown,) which, in case of necessity, is operated in the usualmanner to shift the driving-bell; from the fast to the loose pulley,which elfeets the stopping of the railway-head and doffer. The placingof the belt upon the loose pulley immediately starts the loosegear andclutch part a; but, as the latter is not in contact with the end of thequill, the latter is not rotated. While the dolfer is thus stopped, suchof its teeth as are left at restin the line of movement of the teeth ofthe rotating main cylinder are substantially stripped, and the cotton soremoved is accumulated in a bunch or ridge from end to end of thedol'l'er just below the point where the teeth of the doll'er and themain cylinder pass.

The di'tliculty remedied which made it necessary to stop the doffer andthe railway-head, the operator, just before moving the regularbelt-shifter to replace the driving-belt on the fast pulley, will movethe handle a and the slide-bar 13 sufficiently to move the left-hand endof the quill into engagement with the moving clutch part a", whichlatter will immediately drive he quill in the reverse of its usualdirection of rotation, and, through the gear 4, chain E", and shaft D,will start the dolTcr in motion, but in the reverse of its usualdirection; and the operator, by his hand upon the said lever, will keepthe clutch part a and quill in engagement until the doffer. has beenrotated for about one-fourth of a rotation, or sufficiently to carry thestripped part of the dotfer, before referred to, above the point wherethe teeth of the dol'l'er and main cylinder come in contact. Thisreverse rotation of the (loll'er is sufficient to also place the cottonaccumulated thereon, as described, above such pointof contact. Thisdone, the operator releases the handle a, when the spring 19 effects thedisengagement of the quill from the clutch part a", and immcdiatel ythereafter the operator actuates the usual beltshifter and starts therailway-head and doll'er in the direction of its regular rotation, thespring 19, acting on the rod 13 and finger 12, causing the quill to beforced against the clutch part a. The motion of the doll'er, having beenreversel for a short distance, as stated, before it is started in its.regular direction of rotation, enables the fiber accumulated on thedoffcr, as stated, to be evened and the stripped teeth to again havecotton deposited upon them by the main cylinder; otherwise the sliver atthat part of the doll-er which was stripped, when it comes to the usualdoffcr-comb (not shown) would be completely removed from the doft'er, orthesliver would fail to be continuous beyond the stripped line of thedofler.

The quill and toothed parts cooperating with it at each end constitute aclutch or reversing mechanism or gear; and, having shown one practicalform of reversing mechanism or gear, itself well known in the mechanicarts, I desire it to be understood thatinstead thereof I may employ anyother usual or well-known reversing mechanism or gear which will enablethe doller to be auton'iatically reversed (shaft 1) driven from therailway-head to be reversed) as to the direction of its rotation whenthe lat-tor is first started, and thento permit the said shaft to be runin the direction of its regular or forward rotation, as has beendescribed. The reversal of the usual feeding-rollers in unison with thedofl'er is insufficient to in any manner affect the sliver.

In practice, the shaft B", carrying the under roller of the rollersB",will be provided at its right-hand end, viewing Fig. 1, with a gear,

which will be driven, as usual, from the pinion D through anintermediate, the said gear and intermediate being, however, omitted.

I do not claim a doffer having a motion of rotation coupled with amotion of reciprocation back and forth in the direction of rotation,thus giving to the doffer a constantlyvarying fast or slow speedas, forinstance, in English Patent No. 721 for 1871..

I claim 1. The combinatio11,with the main cylinder, of a dofl'er andmechanism, substantially as described, to automatically rotate thedoffer backward for a short distance preparatory to starting themovement'of the doffer in its regular forward direction, substantiallyas and for the purpose described.

2. The main cylinder of a carding-machine, the dofier, the shaft D, andmechanism, substantially as described, between it and the shaft of thedoffer, to rotate the latter, combined with the shaft H, of therailway-head and mechanism, substantially as described, between it andthe shaft D, to rotate the latter backward for a short distance beforecommencing to rotate the said shaft I) forward, the preliminary reversalof the shaft D effecting the backward rotation of the dof er for a shortdistance, as and for the purpose described.

3. The carding-cylinder, the doffer, a quill, and intermediatemechanism, substantially as described, to rotate the doffer, combinedwith Y mechanism, substantially as described, to rotate the said quillin one and then in the opposite direction,whereby the movement of thedoffer may-be reversed for a short distance prior to being started inits regular direction,

bined with mechanism, substantially as described, to effect theengagement of the said quill and its rotation in the reverse directionon the said shaft H to rotate the doffer in the reverse direction, asand for the purpose described.

5. The shaft H of the railway-head, its fast pulley, and the quill, gear0, provided with the clutch part a, loose on the said shaft, combinedwith the loose pulley having the pinion Z, intermediate 1*, and theshaft d, provided with pinions (1 d whereby the quillv may be rotated onthe shaft H, while the latter is at rest, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
